They do have Finland birch as well in the wings.
With Donnie in charge now I can see them planting Birch trees in the USA.
Also Rotax setting up a line in the USA, I would suggest one to two thousand units a year with the tariff would be substantial. Plus all the other Rotax engines They produce over 200,000 per year, with the US being the biggest consumer. At 50k an aircraft engine, let's say half is the tariff component. That's 7.5k
Your Rotax aircraft engine is now 57500. That's 87,500 AUD.
Makes them cheap in Australia 🤔
